GREATGOLD butterfly valves in a new design

Based on more than 30 years of experience, GREATGOLD butterfly valves have now undergone modernization. This solution builds on a long-proven concept that has been structurally and functionally updated to enhance durability, improve operational performance, and extend service life. The valves are manufactured in Europe and are designed for demanding applications in the water and industrial sectors.

The modernization is primarily reflected in reduced operating torque, enabling the use of smaller gearboxes and actuators while ensuring smooth operation even under a high number of duty cycles. The polygonal connection between the shaft and the disc, without additional pins, ensures torque transmission without backlash or unnecessary losses. A newly designed liner with an innovative profile and self-lubricating material further extends service intervals.
